UNITED STATES ANGELO DE STEFANO, OF RIDGEFIELD PARK, NEW JERSEY.

MUSIC-LEAF TURNER.

Application filed March 8, 1918.

To all tf1/omit may concern Be it known that l, ANGELO Dn STEFANO, acitizen of the United States of America, residing at Ridgeiield Parli,in the county of Bergen and State of N ew Jersey, have invented new anduseful improvement-s in Music-Leaf Turners, of which the following is aspecification.

This invention relates to improvements in music leaf turners and seeksfor its principal object to simplify and reduce the expense ofmanufacture of devices of this character, the same employing a minimumnumber of parts, which effectively operate at all times to accomplish apurpose for which they are designed. l

Another obj' ect of the invention is the provision of a music leafturner which is so constructed as to allow the arms which carry thesheets, to be readily turned in either direction independently of themechanism for operating the same.

Another obi ect of the invention is the provision of a music leaf turnercomprising plurality of swinging arms arranged in superposed relation,an actuator arranged above said arms, means for transmitting motion tothe actuator and a spring pressed trigger vertically movable throughsaid actuator and provided at its lowerniost end with means forsuccessively7 engaging the arms and correlating the same with theactuator' for turning the leaves successively.

lith these and other objects in view the invention resides in the novelconstruction, combination and arrangement of parts, fully described andpointed ont in the following description and claims and illustrated inthe accompanying drawings in which- Figure 1, is a front elevation ofthe device.

Fig. 2, is a horizontal section on the line 22, of Fig. 1, looking inthe direction indicated by the arrows.

Fig. 3, is a vertical section on the line 3 3, of Fig. 1, looking in thedirection indicated by the arrow.

Fig. 1, is a diagrammatic view of the arms and the trigger.

Figs. 5, G and 7 are detail views illustrating the manner in which thearms 14 are moved from one side to the other of the device successively.

Referring to the drawings, 10 designates Specification of LettersPatent.

a base plate w iich is provided with the pivoted clamp 11, the samebeing designed as a means for clamping the device to the stand or otherarticle to which the device is to be applied, and which also serves as ameans for positioning the hook or sheet music thereon. Secured to theplate is a casing` 12, which is provided with a pivot pin 13, extendingvertically therein, upon which are mounted for swinging movement thearms which are provided at their outer ends with any suitable clampingmeans 15, for engagen ent with the music leaves. Each arm le is providedwith an enlargement 14a the purpose of which will appear hereinafter.Mounted above the arms 14, on the pin 13, is an actuator 16, which isprovided with teeth 17, and an outwardly extending arm 'ng a sleeve 19,through which a trigger pm 20, is adapted to slide. The pin is providedat its lower end with an enlarged head 21, having a reduced lue` 22, prjecting downwardly therefrom and the sleeve is provided with enlargedbore at its lower eX- tremitjf forming a shoulder 23, therein betweenwhich and the head 21, is inserted a coi ed spring 2e?, whereby thetrigger is norll projected toward the arms 14, as is shown in Fig. 3 ofthe drawings. The lug 22 is adapted to ride over the enlargement 14: ofthe arms. The lug 22 is of a length equal approximately to the thicknessof either of said arms. rlherefore it is impossible to move more thanone arm at a time. rllhe trigger is provided at its upper ing portion25, and has end lith manipul a stesl pin 26 therein, which is adapted toengage the upper extremity of the sleeve whereby the trigger may belocked in an inoperative position when desired. Extending transverselyof the easing 12, is a bar 27. provided with rack teeth 2S, forengagement with the 17, on the actuator. One eX- tremiti7 '..ic lar 2T,is reduced as at 29, to form a snoulder 3G, between which and the sideof the casing is interposed a coiled s V nag; 31, the purpose of whichis to normally project the bar 27, in one direction. The oppositeextremity of the bar is pro- .'dcd with an opening 52- in which isreceived a HeXible shaft 33, which is )rovided with an operating` head34. This operating means may also be used in com ysation with a footpedal and may be positioned at any point within convenient reach of themusician. si stop member 35, is provided adjacent the pin 13, andprojects upwardly through the bottom of the casing where it is adaptedto be engaged by the arms in either direction to limit the movementthereof. This stop positions the arms with relation to the trigger tocause the same to positively bring` the lug 22, into proper place. rlhelower side and front walls of the casing` are slotted as at 36, toprovide a working space for the arms and the upper wall of the casing`is provided with an arcuate slot 37, which receives and guides the upperez:- tremity et the sleeve 19.

To turn the leaves or sheets of the music to be played individually, theoperating head 34: is moved toward the bar 227 and this action throughthe intervention ot the parts 17, 18 and 19 cause the pin 2O to move inan arc. lnasmuch as the lug 22, in its normal position, is in engagementwith the uppermost arm 1e, the same will be caused to move to its otherextreme position. Upon removal oit pressure on the head 34, the spring`31 will Yfunction to cause the return movement of the pin 2O and in thereturn movement of the pin 20, the lug 22 will ride over the enlargementlla of the next uppermost arm 14l until it clears the back edge thereof,when the spring' 24 will impart a .downward movement to the pin 20causingl the lug 22 to be positioned behind the arm 141. The head 21limits the downward movement of the pin 20. lt will be understood thatthe pin 20 is capable oi reciprocatory, arcuate and turning' movements.

In Fin: 5 one of the arms 14 is shown about to be moved to an oppositeextreme position from over the alined arms beneath.

Fig. 6 is a sectional view taken on the line 6 6 or" Fig. 5. Fig. 6shows the relative disposition of the parts as shown in 5.

Fig. 'Y shows the lug 22 disposed behind the arm 1%2 next lowermost tothe arm 1l being moved as in Fig. 5. rlhe lug 22 never rode off of theenlarged part 14 of the arm 142 until it arrived at the baci; edge ofthe arm 142, at which point the said lug is projected down behind thearm 1&2 by the spring 2li. Such operation is repeated until all of thearms have been moved by the mechanism, when they are returned by hand totheir other extreme positions.

While I have shown and described a simple and preferred form oi? theinvention, l do not care to be limited to the exact details thereinexhibited but desire to reserve the right to make such changes andalterations as liall within the scope of the appended claims.

lWhat l claim is 1. A music leaf turner including a pivot, a pluralityor" superposed leaf turning arms loosely mounted on said pivot, meansfor effecting the movement of said arms singly in succession including aflexible thrust member and a spring pressed pin havinp` a lug` which isengageable with said arms, and a shoulder embodied by said pin wherebythe same is limited in its downward movement.
